A judgment sample, or expert sample, is a type of non-random sample that is selected based on the opinion of an expert.. Results obtained from a judgment sample are subject to some degree of bias, due to the sample's frame (i.e. the variables that define a population to be studied) and population not being identical.
Rather than relying on predetermined formulas or statistical calculations, it involves a subjective and iterative judgment throughout the research process. In qualitative studies, researchers often adopt a subjective stance, making determinations as the study unfolds. Sample size determination in qualitative studies takes a different approach.
Some critics argue that the testing psychologist must also project onto the patterns. A possible example sometimes attributed to the psychologist's subjective judgement is that responses are coded (among many other things), for "Form Quality": in essence, whether the subject's response fits with how the blot actually looks.

A situational judgement test (SJT), also known as a situational stress test (SStT) or situational stress inventory (SSI), is a type of psychological test that presents the test-taker with realistic, hypothetical scenarios. The test-taker is asked to identify the most appropriate response or to rank the responses in order of effectiveness.
Behaviorally anchored rating scales (BARS) are scales used to rate performance.BARS are normally presented vertically with scale points ranging from five to nine. It is an appraisal method that aims to combine the benefits of narratives, critical incidents, and quantified ratings by anchoring a quantified scale with specific narrative examples of good, moderate, and poor performance.
Judgment sampling or purposive sampling, where the researcher chooses the sample based on who they think would be appropriate for the study. This is used primarily when there is a limited number of people that have expertise in the area being researched, or when the interest of the research is on a specific field or a small group.
Free response questions typically require little work for instructors to write, but can be difficult to grade consistently as they require subjective judgments. Free response tests are a relatively effective test of higher-level reasoning, as the format requires test-takers to provide more of their reasoning in the answer than multiple choice ...
